Brief Historical Development and Contributions of Chemistry for Modern Civilization Introduction: As defined by Oxford Dictionary‚ Chemistry is the scientific study of the structure of substances‚ how they react when combined or in contact with one another and how they behave under different conditions . In other words‚ Chemistry is the study of the materials and substances of the world in which we live. The materials‚ which make up the earth‚ sea and air‚ are called raw materials. These include

and molecules interact with each other and how this affects their bonding‚ reactivity‚ 3D structure and physical properties. A number of important topics such as stoichiometry‚ intermolecular forces‚ thermodynamics‚ kinetics‚ equilibria‚ and electrochemistry will be developed in order to prepare students for a deeper exploration of chemistry. The concepts developed within the lectures and workshops are complemented through an extended laboratory program where students will have the opportunity to

Early History of Electric Power Date Event Pictures 1800-1819 Early electric experiments were performed with DC. In 1800‚ Alessandro Volta published a description of a silver/zinc battery‚ acknowledging that he did not know how it worked. In 1807‚ Humphry Davy constructed a practical battery (the picture will be immediately familiar to anyone who works with UPS systems)‚ and demonstrated both incandescent and arc light. • Volta’s famous bi-metalic frog twitch (I did this one myself as a boy..
